Nath Motors provides clean energy
generation through biomass gasification.Biomass Gasifier is a
thermo-chemical reactor where Biomass gasification takes place which is a
conversion of solid fuels(Wood & Agricultural waste etc) into a
combustible gas mixture normally called "Producer gas".

Due
to rapid industrialization and the burning of fossil fuels all over the
world lead to emission of CO2. Contributes 50% of green gas emission One of
the remedies to limit the rising content of CO 2 in the atmosphere is
energetic use of biomass fuel. Biomass is basically an organic material,
which includes wood, crop residues, solid waste, animal wastes, sewage, and
waste from food processing. Biomass is Your browser may not support display

Industrial
Applications of Biomass Gasification

Advantage GasificationIn this process,
biomass is converted into a mixture of gases through a thermo-chemical
reaction called producer gas consisting of combustible gases mainly
hydrogen, carbon mono oxide and methane, non-combustible gases nitrogen,
carbon dioxide and water vapor. The essence of gasification process is the
conversion of solid carbon fuels into carbon monoxide by thermo chemical
process. The gasification of solid fuel is accomplished in air sealed,
closed chamber, under slight suction or pressure relative to ambient
pressure This technology enables you to directly treat Green Wood / Biomass
having moisture content of 10-15% without using a drying process.

Biomass
gasification is completed in many stages that elaborated and explained with
a flow diagram given below

Drying
: Biomass fuels consist of moisture ranging from 5 to 35%. At the
temperature above 100 o C, the water is removed and converted into steam. In
the drying, fuels do not experience any kind of decomposition.

Pyrolysis
: Pyrolysis is the thermal decomposition of biomass fuels in the absence
of oxygen. Pyrolysis involves release of three kinds of products such as
solid, liquid and gases. The ratio of products is influenced by the chemical
composition of biomass fuels and the operating conditions. The heating value
of gas produced during the pyrolysis process is low (3.5 - 8.9 MJ/m 3 ). It
is noted that no matter how gasifier is built, there will always be a low
temperature zone, where pyrolysis takes place, generating condensable
hydrocarbon.

Oxidation : Introduced air in the
oxidation zone contains, besides oxygen and water vapors, inert gases such
as nitrogen and argon. These inert gases are considered to be non-reactive
with fuel constituents. The oxidation takes place at the temperature of
700-2000oc. Heterogeneous reaction takes place between oxygen in the air and
solid carbonized fuel, producing carbon monoxide. Plus and minus sign
indicate the release and supply of heat energy during the process
respectively

Hydrogen
in fuel reacts with oxygen in the air blast, producing steam . H 2 + ½
O 2 = H 2 O + 242 [ MJ/kmol] Reduction In reduction zone, a number of high
temperature chemical reactions take place in the absence of oxygen. The
principal reactions that takes place in reduction are mentioned below.

From above thermo-chemical reaction it may be
understood that heat generated in pyrolysis is absorbed in reduction
process. Hence, the temperature of gas which is very high in the beginning
goes down as it passes through various stages. If complete gasification
takes place, all the carbon is burned or reduced to carbon monoxide, a
combustible gas and some other mineral matter is vaporized. The remains are
ash and some char (unburned carbon).

Gasification for Energy Supply Rural areas in
the developing countries India are characterized by disperse population and
a lack of infrastructure. Energy is the basic mean in improving the living
standard and productivity. Energy is required in household for lighting and
running electrical apparatus such as TV and Radio. Energy is also demanded
in agriculture for operating irrigation pumps and other machinery such as
thresher.
